We pushed out a small update to sheet workers onto the Dev Server today. We've made a minor change to how default attributes are calculated in order to fix an undocumented problem. While we don't officially support having multiple attributes that share the same name, we've resolved an issue where default attributes were not being correctly set if there were more than one attribute with the same name and one was given a default and the other was not. Additionally we've added two more pieces of information to eventinfo for change events. These will now include eventinfo.previousValue and eventinfo.newValue. These are in the same spirit as the eventinfo.removedInfo that was added last month for the removal of repeating sections. The previousValue will give the value of the attribute before the change event that triggered the eventinfo and newValue will give the current value so that you don't need to getAttrs unless you need other information. Sheet authors, we'd appreciate it if you could take a minute to test your sheet works on dev and make sure there aren't any unexpected interactions or issues we need to fix before this goes live with the Fog and Functionality update.
